Thanks for getting on it that fast!   ./configure now runs fine.

I'm now running into a compilation problem with the cvs version -- the
errors are as follows:

In file included from ewald_util.c:50:
../../include/fftgrid.h:79: error: parse error before "rfftwnd_plan"

Looking at the code referenced:

typedef struct {
    t_fft_r *ptr;
    t_fft_r *localptr;
    t_fft_r *workspace;
    int      nx,ny,nz,la2r,la2c,la12r,la12c;
  int      nptr,nxyz;
#ifndef GMX_WITHOUT_FFTW
    rfftwnd_plan     plan_fw;
    rfftwnd_plan     plan_bw;
#ifdef GMX_MPI
    rfftwnd_mpi_plan plan_mpi_fw;
    rfftwnd_mpi_plan plan_mpi_bw;
    t_parfft         pfft;
#endif
#endif
} t_fftgrid;

Is this a problem with the macro defintions, or with the
configuration?  Grepping through the source, I don't see rfftwnd_plan
actually defined anywhere as a type.

Best,
Michael
